Aluminium Composite Panels (ACP) consist of two high-quality aluminium sheets bonded to a mineral core, delivering exceptional lightness, rigidity, and versatility, along with superior flatness, durability, weather resistance, and long-lasting color retention thanks to PVDF coatings.
Perfectly suited for ventilated façades, interiors, and creative cladding, ACP offers effortless fabrication, sustainability, and low-maintenance value, making it a preferred choice for modern architectural projects.

Project Showcase
WILLSTRONG supplied 8,500 m² of 5110/5308 blue/white Aluminum Composite Panels for the USTP Gymnasium curtain wall in 2013. The panels deliver lightweight rigidity, flatness, and weather resistance, transforming the building into a vibrant campus landmark. Custom colour matching and a wide finish range ensure tailored solutions for every architectural vision.
At WILLSTRONG, we offer an extensive range of colours, shines, and textures. Our colorimetry laboratory can precisely match any RAL, PANTONE, or NCS colour, and produce fully customised finishes from a physical sample.
Discover how our finishing collections elevate your projects to a new level of excellence and distinction.









Its unique and classical finish is highly favoured for museums and libraries.

Just like Titanium-zinc, its unique texture provides great possibilities for architects.

Its rich warm tones and natural patina create a timeless finish that ages beautifully.
